The phonon density of states (PDS) of a parahydrogen quantum crystal at liquid-helium temperature and pressures of 0, 80, and 150 MPa was determined from data for incoherent inelastic neutron scattering. An-harmonic phonon damping strongly affects the form of the real PDS in this pressure range. © 1995 American Institute of Physics.
